Dear Tao Effect,
I have been using Espionage for quite a while now and I like it very much.
However, it is a royal pain to use Espionage for my contacts. It usually takes only hours (days at most) until all my contacts are gone. Dead. Address Book won't show any contacts at all. I usually won't be able to add new contacts, either. Sometimes, they will still be accessible from Mail.app, sometimes not. Sometimes it helps to delete `/Library/Application Support/SyncServices/*.*`, sometimes not. Good thing I have backups, since otherwise this would have been awful.
I don't know exactly what is causing this, but I do know that it does not happen if I don't use Espionage. For now, this means I can not use Espionage for my Address Book.
Sincerely,
Bastian (A somewhat disgruntled user)
